It certainly took some brainy guys to shove that color signal into the existing black and white, no doubt about it. Lot more restrictive to have to do it within those limits and not make people throw out their B&W tvs than to be able to start something from scratch like HDTV.
As I see it:
Color TV - got better and better as the sets got better while the signal basically remain unchanged.
HDTV - The cameras and the sets aren't really the problem, the broadcasters trying to skimp on bandwidth with subchannels is. Even a theoretical 'perfect' HDTV set, even if it was a massive picture tube the best that had ever been built, could not help degraded picture from guys trying to do 1080i and then not give it all the juice (bandwidth). If I don't see pixelization then HDTV is wonderful, stupendous, fantastic. When I see pixelization - I start to get ticked off. And pixelization has nothing to do with the sets, only the signal, even if it's coming in 5 by 5.
But - people were ticked off in the old days with picking up color on antennas with ghosting, static, interference, etc., also.
